Final answer:
To find the correct answer, eliminate the option 1/10 and simplify the remaining options. The correct answer is 3/10.
Step-by-step explanation:
To find the correct answer, we need to eliminate the option 1/10. We can then look at the remaining options and determine which one is the correct answer.
Let's eliminate 1/10.
Now, we are left with options a) 2/10, b) 3/10, c) 4/10, and d) 5/10. To determine the correct answer, we can simplify each option by dividing the numerator and denominator by their greatest common factor.
After simplifying, we get:
a) 1/5
b) 3/10
c) 2/5
d) 1/2
Therefore, the correct answer is b) 3/10.
